What is Reactoonz?

Forget reels. This is a 7×7 grid crawling with one-eyed aliens. Link five or more that touch and boom — they detonate, vanish, and new ones crash down to take their place. One spin. A chain of wins. That’s the hook. And it’s high volatility, so when it goes quiet it goes quiet — but when it erupts, hold on tight.

How to play Reactoonz

Zero setup. Slam your bet anywhere from 0.20 to 100, hit spin, and go. No paylines. No manual. Want it fully automatic? Fire up autoplay and watch the carnage unfold. The only thing you care about is the meter on the side — because that meter is where the fireworks live.

Charge the meter, unleash the chaos

Every cluster you blow up feeds the charge meter. Fill a stage, trigger a feature. Fill the whole thing, and the big one drops. Watching it fill is pure edge-of-your-seat stuff.

Features & bonus round

No free spins — and trust us, you won’t miss them. As the meter charges, one of five Quantum Features rips across the grid: some blast symbols into wilds and wipe out their neighbours, some nuke an entire alien type off the board, some slash wild patterns straight through the middle. Then there are the Giantoonz — four matching aliens smash together into a giant symbol that DOUBLES your win. Even dead spins can come alive when the Instability feature machine-guns wilds onto the grid. But the moment everyone screams for? The Gargantoon. Max out that meter and a monster 3×3 wild lands, then splits, and splits again, spraying wilds everywhere. This is the payoff. This is the rush.

Graphics, sound & theme

The aliens are loud, weird and full of attitude. Neon colours pop off a dark grid and the soundtrack builds and builds as the meter climbs, ratcheting the tension until it snaps. Every explosion lands with a punch. It looks and sounds like a party on your phone — and it never gets old.
